METALLIC REINFORCEMENT FOR WALLS.

Original application filed Angust 1, 1910, Serial No. 574,768. Divided and this Serial No. 602,781.

Too whom it may concern:

Be it known that I, WALTER L. COLLINS, residing at Milford, in the county of Worcester and State of Massachusetts, have invented an Improvement in Metallic Reinforcements for Walls, of which the following is a specification.

This application is a division of my application #574,768, filed August 1, 1910.

This invention has for its object to construct a metallic corner reinforcement adapted for use in the wall of my aforesaid application which may be easily and cheaply manufactured and is very strong and durable.

Figure l is a front elevation of a corner reinforcement embodying this invention. Figs. 2 and 3 are sectional details of the same taken on the dotted lines 22 and 33, respectively, of Fig. 1.

The metallic corner reinforcement here shown for the purpose of illustrating my invention consists of a corner bead d, composed of a flat strip of sheet metal folded upon itself and a similarly constructed bead d, and double wire struts 0Z 0Z arranged in sets and connecting said beads together. The strut wires d have an outward curve and the strut wires (1 have an inward curve, and said wires are arranged in pairs and connected at their ends to the folded beads d and cl. The ends of said strut wires are bent at right angles to their bodies, so as to occupy positions between the folds of the beads d and cl for convenience in manufacture. The strut wires 05 and (i may be formed in a single piece. The connecting struts thus formed of Wires are here shown as bent at an angle so that the bead 03 may occupy a horizontal position and the bead d may extend in a diagonal direction toward and to the corner, where it is exposed. In such embodiment of my invention the bead d, is arranged at the side of and in a plane in front of the head (2'.

Copies of this patent may be obtained for Specification of Letters Patent.

Patented Dec. 12, 1911.

application filed January 16,

The reinforcements herein described may be embedded in the plaster of a lath and plaster wall with the bead d at the back side thereof and the bead d at the front side thereof, and when the connecting wire struts are bent at an angle said reinforcements will extend in a diagonal direction from back to front. A

By bending the strut wires some inward and others outward, as here shown, great stiffness is given to the reinforcing strip, which is important when the bead (Z is exposed, as in such case a severe pressure or blow on the bead 03 would not act to distort the strip or parts composing and thereby cause the plaster to crumble.

I claim 1. A metallic reinforcement for Walls consisting of two side strips, and double wire struts arranged between them and connected at their ends thereto, each strut comprising a pair of wires, one having an outward curve and the other an inward curve in the portion extending between said strips, substantially as described.

2. A metallic reinforcement for walls consisting of two strips of sheet metal folded upon themselves, and arranged at an angle with respect to each other, and double wire struts arranged between them and connected at their ends thereto, each strut comprising a pair of wires, one having an outward curve and the other an inward curve in the portion extending between said strips, substantially as described.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

WALTER L. COLLINS.
